Your shipping charges are not too high.
Shipping rates are based on weight and distance. (Fuel surcharges are included)
For example: The UPS cost of a package weighing only 1 pound and shipping from TX to PA would be $6.36 and you would have to drop it off at a UPS location.
If you arrange for UPS to pick it up the package the cost would jump to $ 10.51.

Shipping the same 1 pound package just across town would cost me$ 5.52 at to lowest rate.

Btw. Congratulations on your future grandchild!
I guess we can start calling you grandma now.
